David Benizri, Nicolas Dietrich, Gilles Hébrard Chemical Engineering Science Volume 170, 12 October 2017, Pages 116-121 Abstract The Henry’s law constant is required to size absorption processes. However, its experimental determination for multi-component gases in presence of complex liquids remains problematic in the process industry and research field. This work presents a new experimental setup […]

Abstract : Gas-liquid mass transfer around Taylor bubbles moving in a meandering millimetric square channel was locally visualized and characterized in the present study. For that, the colorimetric technique proposed by Dietrich et al. (2013) was implemented. With this technique, the evolution of equivalent oxygen concentration fields in the liquid slugs passing through one and […]

Abstract: The present work provides an experimental study of the effect of the glycerol concentration on removal performances in a Submerged Aerobic Fixed-Film (SAF) Reactor performing in batch mode. This study consisted in adding various initial substrate concentrations of synthetic solutions (glycerol) in order to assess their effects on biodegradation kinetics and then on bacterial […]

Abstract The aim of this work is to study continuous counter-current absorption of Volatile Organic Compounds (VOCs) by an oil–water emulsion. This process enables the treatment of hydrophilic and hydrophobic VOC within a gaseous effluent emitted by chemical or food processing industries. Toluene was chosen as the pollutant in this work because of its […]

Abstract Quorum Quenching (QQ) has been developed over the last few years to overcome practical issues related to membrane biofouling, which is currently the major difficulty thwarting the extensive development of membrane bioreactors (MBRs). QQ is the disruption of Quorum Sensing (QS), cell-to-cell communication enabling the bacteria to harmonize their behavior. The production of […]
